I feel compelled to attempt to clear up what I see as a few misunderstandings:
1st – J-Cal said:
…as a result My SURE pair, using the ratios of body size and head structure turned out to be reversed.
…oh yea the reason i mentioned sexing is that the new one looks more male to me as I see you guys sex them from pictures.
Brian mentioned when he posted the C-A ratio information that it is not a definitive method, and he is correct. In the same vein, you cannot reliably sex PTS based on pictures.
The most reliable way that I am aware of to sex them is to examine genitalia, and even that is not 100%. If you do manage to pop hemepenes (difficult in adults) you can be certain you have a male, but failure to do so doesn’t automatically indicate a female.
Someone mentioned blood tests earlier. This would be an even more reliable method. I’d love it if whoever posted that could post some info on what lab is doing the tests (especially since I have a suspected female that I would love to verify).
2nd – as to keeping Corucia in community situations – there seems to have been a misunderstanding. James Wilson wrote:
…I did not say that colonies do not work, I said they need to be monitored closly.
And Jean P wrote:
…but to say Brian is the only person to experience harmony within an established Circulus would be an incorrect assumption.
James is not saying (if I understand him correctly) that Corucia can’t reliably be kept in a community tank. He’s just saying that they can’t always be kept that way. There have been instances of individuals living harmoniously one day and killing each other the next. It is a risk all keepers need to be mindful of. It is also a risk that some might not be willing to take.
Sorry if I'm intruding, just couldn't help myself.
